I'm new to developing. I'm creating a public visualforce web-to-lead site. I want to pass values to Company, Lead Source, and probably a few others. I tried following a few examples (the /script portions of my VF page is where I tried to pass a value but it's a complete failure). My guess is that I need to establish components and then assign them somehow to the Lead fields.

Any info on how I can prepopulate those values would be great.

My Extension

public class myWeb2LeadExtension {

    private final Lead weblead;

    public myWeb2LeadExtension(ApexPages.StandardController
                                stdController) {
       weblead = (Lead)stdController.getRecord();
    }

     public PageReference saveLead() {
       try {
       insert(weblead);
       }
       catch(System.DMLException e) {
           ApexPages.addMessages(e);
           return null;
       }
       PageReference p = Page.ThankYou;
       p.setRedirect(true);
       return p;
     }
}

My VF page 

<apex:page standardController="Lead"
           extensions="myWeb2LeadExtension"
           title="Contact Us" showHeader="false"
